In the clinical trial recently published by Moench et al (Langenbecks Arch Surg. 2014) they studied the intraoperative time of hemostasis evaluated at 3 minutes by a non-inferiority design. The collagen hemostatic agent Sangustop ® proved to be as effective as the fibrinogen and thrombin sponge Tachosil ® in times of intraoperative hemostasis (n = 128).
